Abstract

The invention discloses a fan operating controlled system, which is characterized by the following: comprising a electrical source, a controlling switch circuit, a switch controlled signal sending unit and a fan circuit component; sending a nominal electric force with power; electric-connecting the controlled switch circuit to the power; electric-connecting the switch controlled signal sending unit system to the controlled switch circuit; sending a power controlled signal to the controlled switch circuit; electric-connecting the fan circuit element to the controlled switch circuit; passing the nominal electric force through the controlled switch circuit; adjusting to a controlled power; sending to the circuit component of the fan; driving at least one fan to rotate in the fan circuit component; controlling the controlled power with the power controlled signal.

Description

technical field [0001] The invention relates to a fan operation control system, in particular to a fan operation control system which can control the fan to reduce the noise generated by the operation during an initial operation stage. Background technique [0002] In general electronic devices, in order to improve their operating efficiency, most of them are equipped with a heat dissipation system, so as to reduce the high temperature generated by the internal components of the electronic device during operation, so as to improve the overall operating performance. Especially for computer devices, in order to effectively increase the operating efficiency of various electronic components, most of them are equipped with fans and heat dissipation components. Among them, the heat dissipation components usually use heat conduction to directly absorb the heat energy generated by the operation of electronic components, and then use the operation of the fan to generate convective ai...
